Fluorophores for Excited-State Intramolecular Proton Transfer by an Yttrium Triflate Catalyzed Reaction of Isocyanides with Thiocarboxylic Acids

Qian Wang, Jieping Zhu, Shuo Tong, Shun Zhao, Qing He

Discovery of new chemical reactivity of a given functional group can often result in innovative synthesis of important chemical entities that possess unprecedented properties. We designed and developed a one-step synthesis of 5-amino-4-carboxamidothiazoles ...

Synthesis and Structure of Nitride-Bridged Uranium(III) Complexes

Rosario Scopelliti, Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

The reduction of the nitride-bridged diuranium(IV) complex Cs[{U(OSi((OBu)-Bu-t)(3))(3)}(2)(mu-N)] affords the first example of a uranium nitride complex containing uranium in the +III oxidation state. Two nitride-bridged complexes containing the heteromet ...

A small electron donor in cobalt complex electrolyte significantly improves efficiency in dye-sensitized solar cells

Lei Zhang, Ulf Anders Hagfeldt, Yan Hao, Yasemin Saygili

Photoelectrochemical approach to solar energy conversion demands a kinetic optimization of various light-induced electron transfer processes. Of great importance are the redox mediator systems accomplishing the electron transfer processes at the semiconduc ...

UV and IR Spectroscopy of Cold H2O+-Benzo-Crown Ether Complexes

Thomas Rizzo, Yoshiya Inokuchi

The H2O+ radical ion, produced in an electrospray ion source via charge transfer from Eu3+, is encapsulated in benzo-15-crown-5 (B15C5) or benzo-18-crown-6 (B18C6). We measure UV photodissociation (UVPD) spectra of the (H2O·B15C5)+ and (H2O·B18C6)+ complex ...

Gradual release of strongly bound nitric oxide from Fe2(NO)2(dobdc)

Wendy Lee Queen

An iron(II)-based metal-org. framework featuring coordinatively unsatd. redox-active metal cation sites, Fe2(dobdc) (dobdc4- = 2,5-dioxido-1,4-benzenedicarboxylate), is shown to strongly bind nitric oxide at 298 K. Adsorption isotherms indicate an adsorpti ...

Gd(DOTAlaP): Exploring the Boundaries of Fast Water Exchange in Gadolinium-Based Magnetic Resonance Imaging Contrast Agents

Lothar Helm, Shima Karimi

Here, we describe the synthesis of the single amino acid chelator DOTAlaP and four of its derivatives. The corresponding gadolinium(III) complexes were investigated for their kinetic inertness, relaxometric properties at a range of fields and temperatures, ...
